I have a yard full of rocks I don't want. I'm using a shop vac to vacuum them up and dumping them into sandbags. I'm charging $5 per bag, 5 bags for $20. I have a work glove in one of the pictures for scale. I'm using a sifter to try and keep dirt and grass debris to a minimum but won't guarantee there won't be any. The bags are 14x26 inches and I'm filling them about 3/4 full.
